TEGIWA 74mm throttle body for Honda K-Series engines, after a time in R&D we are happy to release our own 70mm throttle body to support the K-Series Platform. Made from billet aluminium and anodised in black for durability, also featuring a dual bolt pattern, this is a great addition for your ported intake manifold. An adapter plate is only needed for the RRC and OEM FN2 manifold.
